Type K copper tube is color-coded to distinguish it from other types. What is its color code?

Type K copper tube is identified by its green color code. This color-coding system is important for quickly recognizing the different types of copper tubing, as each type serves specific purposes based on its wall thickness and pressure rating. Type K has the thickest wall, making it suitable for applications that require higher durability and pressure capacity, such as underground installations and hot water systems. The green color code ensures that anyone working with these materials can easily differentiate Type K from Type L and Type M copper tubes, which are color-coded differently. This standardization helps maintain safety and efficiency in plumbing and pipe fitting practices.
